First roughly surveyed from the ground by British Graham Land Expedition (BGLE), 1936–37.
Photographed from the air by Ronne Antarctic Research Expedition (RARE), November 1947.
Resurveyed by Falkland Islands Dependencies Survey (FIDS), November 1958.
The name, applied by the United Kingdom Antarctic Place-Names Committee (UK-APC), arose because both the BGLE and the FIDS sledging parties had to relay their loads through this area to the head of Prospect Glacier.
